Vaporizer heating element



Sept. 28, 1954 M. KATZMAN VAPORIZER HEATING ELEMENT Filed July 10, 1952INVENTOR. Max Karl/77g W? A T TOR/VESS Patented Sept. 28, 1954 UNITEDSTA OFFICE 1 Claim.

This invention relates to Vaporizers and more particularly to heatingelements used in conjunction therewith.

An object of this invention is to provide an economical, readilyassembled vaporizer heating element.

Another object is to provide a ceramic cover for a vaporizer which willsupport the heating element and its accompanying parts.

Other objects of this invention will be apparent from the followingdescription taken in connectionwith the drawing, in which Figure 1 is afront plan view of my device partly cut away to reveal detail partsthereof;

Figure 2 is a bottom view of the parts shown in Figure 3; and

Figure 3 is a sectional view taken on lines 33 of Figure 2.

Referring specifically to the drawings, a vaporizer container 5 has athreaded neck 6 at its upper end which is engaged by the cover holddownring 1, to secure cover 8 in position with respect to the container 5.Between the neck 6 of the container 5 and cover 8, a ring washer 9 ispositioned to provide a seal between these two members respectively. Thecover 8 may be mold-- ed from ceramic material and has a spout Illincluding a passage lEla in communication with the inside of thecontainer 5, so that the vaporized medicant from the container 5 maydischarge therethrough and into the atmosphere.

Additionally projecting from the cover 8 is bracket I! which functionsto guide and support the electrical connector (not shown) used inconjunction with this apparatus. The cover 8 is provided with a pair ofholes through which the heating element terminals l2 and [3 project.

These terminals are fashioned with rounded tops and threaded lowerportions inset from their main body portion and are spaced from theupper side of top cover 8 by washers M which engage the terminals attheir inset portion. The threaded segments of terminals l2 and I3 engageheating electrodes 18 and 19 to support them and electrodes incasingmember [6 in a manner hereinafter set forth.

Heating electrode incasing member I6 may be molded from ceramic or thelike material and incorporates a T-shaped slot 20 efiectivelysurrounding the electrodes l8 and It on three sides. At the upper sideof the points of the Tare passages 2i and 22 through which threaded endsof terminals 12 and 13 project. The heating electrodes l8 and 19 areinverted L-shaped and are constructed from copper or any otherelectrically conductive material. The feet of the inverted L electrodes18 and I9 engage th cross-member of the T slot 26 of incasing member I6and have terminals l2 and i3 threaded thereinto. Thus it may be notedthat the terminals 12 and I3 support the heating electrodes and theirincasing member [6 from the cover 8. A Washer I1 and the ring washer 9are situated between the cover 8 and the incasing member It.

The lower portion of member it has a passage 25 included therein toinsure free flow of the medicant around the heating elements.

I have described what I believe to be the best embodiments of myinvention. I do not wish, however, to be confined to the embodimentsshown, but what I desire to cover by Letters Patent is set forth in theappended claim.

I claim:

In combination with a vaporizer housing having a threaded neck portion,a disc-shaped cover for said vaporizer housing, a hold-down ring adaptedto engage said cover and be threaded on the neck portion of saidvaporizer housing, a pair of terminals seated on said cover andprojecting therethrough, inverted L-shaped heating electrodes threadedon said terminals, an elongated T-shaped incasing member surroundingsaid electrodes on three sides, the feet portion of the electrodes beingnestled in the cross portion of the incasing member, said constructionand arrangement being such that the incasing member is supported by saidelectrodes, and a passage in the lower end of said incasing member.
